Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floating fender used for a quay of a port or between ships.

[0002]

2. Description of the Related Art As shown in FIG. 10, the surface of a conventional floating type fender is protected by a protective net. The protective net is one in which an automobile tire 2 is connected to the outer peripheral surface of a fender 1 containing air using a metal chain 3 in a net shape, and both end portions of the metal chain 3 are mooring brackets 4. Are linked by.

However, in such a protective net, since the metal chain 3 is exposed on the surface, the metal chain 3 scratches the painted surface of the ship when the ship is in contact with the fender. May get on or peel off the paint. Therefore, recently, the actual Kaihei 3-182228 and the actual Kaihei 4-67.
No. 592 developed a cover that covers the periphery of the fender, and as shown in FIGS. 11 and 12, the metal member is not exposed around the body of the fender.

[0004]

However, in such a conventional technique, although the fender has sufficient strength by itself, the cover causes the fender by an unexpected external force. It is provided to prevent damage, and materials of equal strength are duplicated, which is very wasteful in terms of strength.

Further, generally, mooring fittings for connecting the mooring chain are attached to both ends of the fender, but the mooring fitting is subjected to a very strong pulling force from the mooring chain. The mounting part must be sufficiently reinforced, and the fender itself to which it is attached must be strong enough. On the other hand, in the structure in which the mooring chain is connected to the cover, a hook part that is folded back in a ring shape is formed at the end part of the cover, the rope is passed through this hook part and both ends of the rope are connected, and the shackle is attached to this rope. The mooring chain is connected with the mooring chain.Because a very strong tensile force is applied to the mooring bracket, the cover must have the same strength as the fender,
As a result, as described above, it is a wasteful cause that the same materials are duplicated.

[0006]

Therefore, according to the present invention, a tube bulging into a predetermined shape is formed of an elastic material, and a cloth or metal is embedded between natural rubber or synthetic rubber to form a sheet or bag. , Fixing the mooring metal fittings as the outer cover,
It is characterized in that the tube is covered with this jacket to form a double structure.

[0007]

[Advantage] According to the above construction, the tube has a predetermined shape retention and a cushioning function as a fender, and the outer cover has various effects such as connection with the mooring chain, impact resistance and durability. Corresponding actions will be performed, and the tube and the outer sheath will share the respective actions and fulfill the function of one fender.

It has a structure in which binding holes 8 are provided at the end of the portion 6a and the end of the end covering portion 6b, respectively. At the end covering portion 6b, a mooring metal fitting 10 for connecting the mooring chain 3 is bolted, pinned or It is firmly fixed by vulcanization adhesion or the like.

According to this structure, the tube 5 is attached from the end of the body portion covering portion 6a and is inflated into a predetermined shape by introducing air, and the end portion covering portions 6b are fitted to both ends of the body portion covering portion 6a.
The binding rope 7 is passed through the binding hole 8 and the both are integrated to be integrally formed. Although the number of the tubes 5 is one in each of the above-mentioned embodiments, the number of the tubes 5 packed in the outer cover 6 is not one, and a plurality of tubes 5 may be packed in the same manner as described above.

According to the structure shown in each of the above-mentioned embodiments, the tube has a predetermined shape retention and a cushioning function as a fender, and the outer cover is used to connect with the mooring chain, to provide impact resistance, durability, etc. Therefore, the tube and the jacket share the respective functions, and thus the tube and the outer cover function as one fender.

[0019]

According to the present invention described in detail above, a tube swelling into a predetermined shape is formed of an elastic material, and a cloth or metal is embedded between natural rubber and synthetic rubber to form a sheet or bag. However, by fixing the mooring metal fittings to form a jacket, and by covering the tube with this jacket to form a double structure, the tube is made of a soft and flexible material without any tensile force applied to it. It can be formed in a predetermined shape, so that the tube can be protected by the outer jacket and the mooring fitting for connecting the mooring chain can be directly attached to the outer jacket.

Further, since the mooring metal fitting is directly attached to the outer cover, even if the mounting portion of the mooring metal fitting is not directly related to the tube, the shock absorbing function as the fender immediately disappears. The effect is that it should not occur.
